Big fan of the sf (and previously, sp) spatial packages in R.
I see spTransform and st_transform as methods to reproject a spatial object into a new space. However, I have a case where I have a complicated spatial polygon object centered on a point. I'd love to not have to (inefficiently) recreate the spatial polygons from scratch at a new point (doing this for many census units centroids), but "recenter" the entire object iterative over each point. Any suggestions on how best to do this with sf (or worst case, going backward, sp) objects?
